struct { ... } CommonRegisterMapFloat::C001_SN

Serial number of the inverter

Please note, that the inverter serial number is not supported on all devices and also depends on the internal inverter controller‘s production date and its software version.

If the inverter serial number is not supported, then two fallbacks are implemented that are still unique but may not match the inverter serial number printed on the nameplate:

1: Serial of inverter controller (PMC) if supported 2: Unique ID (UID) of inverter controller

For SYMOHYBRID inverters the inverter serial number is not supported and this register always contains one of the two implemented fallbacks.

Please note further that due to startup timing issues or synchronization faults this field may change its value during operation from one option to another, e.g. at boot time only UID is available and after some time device information is synchronized then this field changes from UID to PMC or inverter serial number.

struct { ... } CommonRegisterMapFloat::C001_Vr

SW version of main device

Returns

i.e. Firmware version of inverter, meter, battery etc.
